To all whom, it may concern." f

Be it known that I, LOUIS MYERs,'a citizen of the United States, residing at Newark, inV

the county of Essex and State ofNeW Jersey,

.have invented certainl new and useful lmprovenieuts in Spring-Operated Fan-Motors;

and I do hereby declare the' following to be a full, clear, and exact description of the invention, such as" will enable others skilled in the art to which ,it appertains to make and use the same, reference being had to" the accompanying drawings, and. to figures of reference marked thereon, which forma part of this specification. v

The objects of this invention are to provide a spring-rmerated fan whiclnwill be more compact in its construction an'dmore regular 1n its movements and'will have a period of movement of greater duration; to enable additional springs to be employed where greater duration is desired without materially changthe transmitting means for transferring the movements from the springs to the fan; to secure'a more simple construction and one inexpensive tonanufacture, and tb secure other advantages and results, some of which may be referred to hereinafter in connection with the description of the working parts.

I 'he invention consists in the-improved spring-operated fan, the motorthereof, and

k1n the arrangements and combinations of parts of the sarde, all substantially as will be hereinafter set fcrtffand iinally embraced in the clauses of theclaim.

Referring to the accompanying drawings, in

which'like figures of reference indicate correspending parts in each of the views, Figure 1 is an elevation of the improved motor, arts of the "casing at the base .of the device fieing broken away to show in section anddisclose the interior parts more clearly. Fig. 2 isfa central vertical section of the same, and Fig.

s n l u 3 1s a horizontalsection taken at' line ln said drawings, v5 indicates the base-casing, which is preferably a single [integral casting open on the under side andiI having atA its ulpper part a small chamber ,l 6 to receive c ockwork by means of which the power is transmitted from the springs and their imme-Y dlate connections to a power-shaft 7, extend-2 ing vertically abovesaid base-casting, dicated in Flg. 2; u

, The lower part of the base-castin is preferably'made wider, as at 8, `than t e upper part containing the clockwork to receive the springs and their attachedparts. The botas in- 'wheel being tom-opening permits the said springs to be withdrawn through the said bottom, and the exposed parts of the casing are not marred in f appearance by such openingand means for closing the same. The said bottom-openmg is closed by the bottom-plate9, which is fastened atl its edges by means of screws, lugs,

or any othery suitable fastenings. (N ot shown.) To the under side of said bottomplate 9 are secured rubberlegs 10, by means of which the device may be seated'upon a ta- I ble or other piece of furniture "Without injury `to the said furniture, and the vibration of the moving machinery within the'device is thus deadened and `objectionable sound prevented. rPhe said bottom plate 9.. at its centerl provides a bearing for a centerl shaft 11, which stands erect on said bottom-plate and at its lowerend is provided with a ange 12,

upon which a spring-carrying plate 13 is secured by brazing, rivets, ,or other suitable means. Above the'said flange the said center shaftis preferably provided with a cone or runway 14 for balls 15, and on said balls is arranged a loose hub 16 of a seeondspringcarrying plate 18. The said hub 16 is provided at its lower end with a suitable annular groove to receive said balls 15 and permit of a running ofthe same. The saidl spring-carrying plate 1 3 is furnished with and supports tened to said plate near its periphery.

.a coiled spring 417, one end ofgwhch is fas- At' the peripheryof the spring-carrying plate 13 the same is preferably turned upward, as: at 20, to provide a bearingr -agaili'gt which the spring may be riveted, as indlcatec" in Fig. 2. The said.` spring-carrying plate ia preferably in the form of a star-wheel to secure lightness and' reduce friction at the edges of the spring the radial arms of the ,said starturned up at their extremities to provide the bea ugs 20, above referred to.

' The inner 'end of the spring 17 is fastened to the hub 16, and thus the tension of the springis transmitted from the said hub 16 to ter shaft 11. lPower is received by thehub 16 from the second spring-carrying plate 18, fastened thereto, which second plate is similar in. construction to the spring-carrying plate -13, and the spring' 171 therein is in like v manner fastened at the periphery of the plate 18 and to the hub 21 of a top'plate 2.2` The said top plate 22 may bea third spring-'carrying'plate-if I desirev a longer movement of TOO 'thegearrying-plate 13 and thence to the cen-l `the parts; but as a-minimum' two springs are able manner. u

lower end to receive the balls 211, lying interordinarily desired. It will be, thus understood that I arrange the supported springs 1n a vertical series, and said springs and their plates may be increased or diminished in' y mediate of the hubs, and at its upper end is The center shaft 11..::t its upper eid is threaded "to receive the con e-nut and lock-nut and also i bears directlyT lfrom, a bracket 29, removably fastenedjn' lturn to a plate 30, rigidly but removably seto receive a first gear-wheel 28 of the clock- 5 work. Said shaft 11 at its upper extremity in or upon., but is removable curedlto the under side of a shoulder 31, cast or formed in connection with the base-casing 5. The movement effected by the springs 17 171 and center shaft 1]. is transmitted from the said first gear-'wheel--28.,.through the series of wheels, as follows: From the said wheel`28 the power is traiitsinitted to the pin. I ion 33, shaft 34, large cog-wheel 35, small t ion 36, shaft 37, cog-Wheel 38. small pinion.

pin-

c39, shaft 40, cog-wheel 41:, and so to pinion 42 on the vertical power-shaft 7, the movement of the center shaft 11 being greatly increased or quickened by the cog-Wheels and pinions to produce a very rapid movement of the said shaft 7.

Near the lower end of the shaft 7, above the top of the base-casing 5, theI same isprovided with a cone-collar 44, which rests upon balls 45, arranged in vrunways at the upperl end-,of an'adjustable support, preferably a hollow screw 46, removably secured within. threaded bearings at the center of the`top of the casing 5. At said center of the casing 5 is secured a h llow vertical post or top casingv 47, through w ich the power-shaft 7 extends, landnear, the top of said post 47 isan interior bearing plate or disk 48, having'runways for balls 49, and at the top of said shaft 7, adjacent to the bearing-disk, is a cone 50, which provides 'similar coperating runways for the balls 49. At the upper extremity of the shaft l7, above said plate 48, is fixed a beveled o*ear-wheel 51, which engages with the second beveled gear-wheel 52 on a horizontal shaft 53, adapted to carryv a fan., (not shown,) or

said horizontal shaft may have other connections lthan the blades` of a fan. The said shaft-53 is 'pleferably arranged on ball-bear- .ings 54, the said ball-bearings being in engagement witlfcones55 and A.56 on said shaft and cooperating with hollow adjustable bear- Th i produce a friction adapted to stop the rota tion of said shaft. y

To wind the springs 17 171; I have pro'- vided a winding-'arbor 64, having bearings ,f within the casing 5 and having atitslinner grooved, :xs at 24, to receive the balls 25 for a cone-nut 26, which latter is preferably locked "in position. by a suitable lock-nut 27.

whence it is transmitted tothe spring-carrying plate 18, hub 16, spring17, and-lower spring-carrying -plate 13 to the shaft 11. Back motion is prevented by means lof. a ratchet-wheel-67 and pawl 68, ir. any suitable man11er.

In operating 4the device power is storedin the springs by winding the shaft 64 and its connections, andsuch power is transmitted from the springs through-the clockwork and vpower-shaft to lthefvertical shaft, whichv is free to expend such power, except when held by the friction-shoe 63. r

Itis manifest that the formand construction of the'hollow post 47, as shown in Figs. 1 and. 2, with an enlarged spherical head to contain the gearing which transmits rotation from the'vertical shaft 7 to horizontal shaft 53- and with lateral extensions 59 60 to reoeive the tubular bearing-sleeves57 58 adapt the. hollow post to serve to the best advantage as ajhandle in' manipulating the device and carrying it fromplace to place. This isa matter of practical importance in-such a. `fan-motor having a massive and heavy base to impar-t stability. f
